【摘要】：随着汽车电子技术的迅猛发展,现代汽车朝着智能化、绿色节能、安全舒适的方向加速前进,越来越多的车载电子设备进入汽车,如车载电器、车载多媒体、车载导航、车载仪表终端等。汽车性能在得到改善的同时,车载电子设备的加入,使得驾驶员的操控对象急剧增加,加大了驾驶操作的复杂度,增加了行车安全隐患。随着语音识别技术和嵌入式技术的迅速发展,使得利用语音指令代替部分手动的操作进行车载电器的操控成为可能。驾驶员可以通过语音指令对车载电器操作控制,并结合车载前屏终端实时、直观地看到操作结果,从而减轻了驾驶员的操作负担,在简便、安全地完成车载电器操控的同时,也极大的提升了驾驶的舒适性。本文以车载电器为控制对象,提出一种基于HMM算法的嵌入式非特定人车载电器本地语音控制终端系统设计方案,以内核为ARM1176JZF-S嵌入式微处理器S3C6410A为车载电器主控平台,采用基于LD3320的语音识别模块,以群创10.1寸TFT-LCD触摸屏作为车载前屏终端,软件开发平台基于Linux2.6.38和Qt4.6。在构建系统硬件及软件平台的基础上,实现了非特定人车载电器语音控制终端系统样机研制,系统能够完成非特定人语音指令的识别和对非安全性车灯、电动车窗、车载音响、车载空调、雨刮器等车载电器的集成语音控制,并在车载前屏显示终端实时显示操作结果。同时也可采用手动的方式进行车载电器操作控制,且手控优先于声控,为驾驶安全性提供保障。系统还针对车载环境进行了相应的抗干扰优化设计,提高了系统的可靠性。最后,在终端样机上进行了系统的性能测试实验,实验结果表明,系统具有识别率高、实时性好、操控及显示准确、显示界面友好、可扩展性强等优点。
[Abstract]:With the rapid development of automobile electronic technology, modern car toward the intelligent, green and energy saving, safety and comfort in the direction of speeding up, more and more vehicle electronic equipment into the car, such as electric vehicle, vehicle multimedia, vehicle navigation, vehicle instrument terminals. Cars can get improved at the same time, join the vehicle electronic equipment. The driver control object increased dramatically, increasing complexity of driving operation, increased traffic safety problems. With the rapid development of speech recognition technology and embedded technology, makes use of voice commands instead of manual operation may become part of the electric vehicle. The driver can control through voice commands for electric vehicle operation control, and combined with the vehicle the front screen terminal real-time, intuitive to see the results of the operation, thereby reducing the burden on the operation of the driver, simple and safe completion of electric vehicle The operation at the same time, but also greatly enhance the driving comfort. The electric vehicle as a control object, put forward a kind of embedded HMM algorithm based on the local electric car voice control design scheme of terminal system, the kernel for ARM1176JZF-S embedded microprocessor S3C6410A for electric vehicle main control platform, the use of voice recognition module based on LD3320 to, Innolux 10.1 inch TFT-LCD touch screen as the vehicle front screen terminal, based on the software development platform of Linux2.6.38 and Qt4.6. in the foundation of system hardware and software platform, realizes the prototype system control terminal speakerindependent vehicle electrical system can recognize speech, speech and instructions for non safety lights, electric the window, car audio, car air conditioning, wiper and other integrated voice vehicle electrical control, operation and display in front of car display terminal in real time Results. At the same time also can use manual way of electric vehicle operation control, and manual control prior to control, to provide protection for the safety of driving system for vehicle. The anti-jamming corresponding optimization design, improve the reliability of the system. Finally, the performance test system in terminal prototype, experiment the results show that the system has high recognition rate, real-time, accurate control and display, friendly display interface, scalability and other advantages.
